, while the latteris screw threaded externally att32 and formed with vertical'slot-ho les.33 ,for guiding theinner sliding stop 34;,loosely mounted on the-plunger-spindle of the. rod 26,.Wh1ch sliding stop 34 is adjustable in a vertical direction through the medium of a hand-wheel 35,.m'ounted on. the-screwed portion32 of the sleeve 28. 7

A means for lockin the treadle 19 in the position into which it as been placed is pro-' vlded in connection with the two-part adju stabl'e rod, (see Fig; 3,) comprisin a screw 36, attached to the rod 26, passingt ou h a vertical slot 37, formed in the sleeve 28,-w "ch.

so that the sliding brush-carrying member '5 is rendered practically inoperative. The

sliding sto 34 of the two-part rod isn'ow adjusted' so t at the distance of the downward travel of the plunger 31 before coming onto the adjusted stop 34 is equal to that of the distance of'the desired travel of the brush7, and then upon depressing the treadle-lever 19 the bell-crank lever 15 is rocked and the jointed rod 9 straightened by the movement of the radius-arm 17. The brush-carrying member is then'rapidly reciproeated in a vertical direction, and on a form of type with the flong in position thereon being placed on the table-2 under the reciprocating brush -7 a matrix of even character is speedily produced, while, if desired, the treadle-lever 19 may be locked in the down position when the machine is inaction by fixing the rod 26 to its sleeve 28 through the medium of the screw/36, and then the manual pressure on the treadle-lever 19 can be removed.
